Don't own this pistol so sorry, don't have the answer.Can someone tell me what parts were included in the case when you purchased your shadow 2? Just got mine today. I thought that springs were included. Also, the larger safety lever was installed and included another lever the same size. Could this be a quality control issue when packaging? Just let me know what came with yours.
You could call CZ USA and ask them. Searched them to get their phone number. And they were nice and helpful.
Good Luck. Hope you find what you are looking for.
Would be great if you could Post a Range Review for your pistol. I don't have the SHADOW 2 SA so it would be interesting.
